Nikkei 225 Falls 0.8%, Topix Down 0.3% at Morning Close

The gap between the two benchmarks is the detail worth noting: the Nikkei's heavier fall versus the Topix points to weakness concentrated in the large-cap, export-oriented names that dominate the Nikkei, rather than broad-based selling across the Japanese market. That distinction matters for anyone reading the move as a signal on Japan risk appetite more generally, since a narrower decline suggests the pullback is not uniform. Whether the Topix continues to hold up better than the Nikkei through the afternoon session is the open question.
